以音频播放过程为例,阐述了数字音频信号在处理器 Intel Xscale pxa270与音频芯片 Philips UDA1341TS 之间的数据传输过程。对音频电路进行硬件设计,并在 Visual Studio 2005上进行软件编程,最终在支持 win CE 操作系统的 Edukit-IV 嵌入式实验平台上实现了数字音频的录入和播放等功能。
以音頻播放過程為例,闡述瞭數字音頻信號在處理器 Intel Xscale pxa270與音頻芯片 Philips UDA1341TS 之間的數據傳輸過程。對音頻電路進行硬件設計,併在 Visual Studio 2005上進行軟件編程,最終在支持 win CE 操作繫統的 Edukit-IV 嵌入式實驗平檯上實現瞭數字音頻的錄入和播放等功能。

By using the audio playing process as an example,the data transmission process of digital audio signal between the Intel Xscal 270 processor and the Philips UDA1341TS audio chip was introducee. The hardware of the audio circuits were designed and the software programming was operated in Visual Studio 2005.The audio recording and playing functions can be achieved in the Edukit-IV embedded experi-ment platform that supports the win CE operating system.
